    Comments about NGK Laser Iridium Spark Plug (IFR6L11):

    I replaced the plugs on my 2011 Outback 2.5 engine with 48,000 miles. Advanced auto selected the right plug (exact replacement that was in the car new) and I had the plugs in two days with free shipping! Discount code work perfectly! Plugs went in easily, once air filter housing was removed. No special socket extentions needed, plugs torque down easily the first time. You could see the wear on the old plugs almost entirely on the ground element. It was almost half gone. Advanced Auto got this done fast, good price and got it right, the first time!

    • Q:

      Is this plug gapped when shipped. If so, what is the gap?

        A:

        Hi David, great question! This is a universal spark plug and not vehicle specific. Although the NGK factory will set the gap to a pre-selected setting, this may not be the right gap for your particular engine. It is always best to check the gap against the manufacturer's specifications. If adjusting the gap on fine wire or precious metal plugs such as platinum or iridium be very careful not to apply any pressure or prying force to the fine wire center electrode or insulator as they can be damaged. The gap should be adjusted by only moving the ground electrode.
